Description

Technical Field

[0001] The utility model relates to the technical field of missile launch tubes, and particularly relates to an assembly tooling for launch tubes. Background Art

[0002] Common composite material cylindrical launch tube structural parts are divided into two categories: mechanical connection and bonding.

[0003] For the form of mechanical connection structural parts, usually, numerical control machining is first carried out on the composite material cylinder body. Positioning holes and positioning surfaces of the structural parts on the cylinder body surface are milled on the cylinder body surface. After installing the metal structural parts on the inner and outer surfaces of the cylinder body through the holes and surfaces, numerical control machining is carried out on the metal structural parts on the cylinder body surface again to achieve product accuracy.

[0004] For the form of bonding structural parts, usually, a laser tracker is used for measurement and installation. A space coordinate system is established with the cylinder body itself as the reference, the relative position between the structural parts and the cylinder body is adjusted, and the structural parts are bonded and fixed after being in place.

[0005] This method of positioning and installing structural parts through numerical control machining can meet the manufacturing accuracy requirements. However, due to the large structural size and weight of the composite material cylindrical cylinder body, the distribution of the structural parts on the surface is relatively scattered and the regularity is not high. In order to machine the positioning holes and surfaces at different angles of the cylinder body, the cylinder body needs to be rotated multiple times during the numerical control machining process, and the machining reference needs to be re-aligned for machining. Each alignment will cause a certain deviation in the machining reference, resulting in inconsistent installation references for the structural parts at different angles on the cylinder body surface. Measuring and installing through a laser tracker and numerically controlling machining to rotate and align the reference multiple times are extremely time-consuming, affecting the production efficiency of products and being not conducive to batch production.

[0033] As Figures 1-9 shown, an assembly tool for the surface structure of a composite cylindrical launcher tube includes:

[0034] A cylinder support frame 100 for installing a cylinder surface support assembly 200, a cylinder end face limiting assembly 300, and a structural member assembly tool assembly 400;

[0035] The cylinder surface support assembly 200 is used to support the cylinder body and includes a support seat 201 that fits the cylinder surface;

[0036] The cylinder end face limiting assembly 300 is used to restrict the axial position of the cylinder body and includes a restraint base 301, and a restraint ring 302 for inserting into the end of the cylinder body is provided on the restraint base 301;

[0037] The structural member assembly tool assembly 400 is used to install the structural member to be assembled onto the launcher tube and includes a support column 401, and a moving member 402 is installed on the support column 401, and the moving member 402 is used to drive the structural member to approach or move away from the launcher tube body.

[0038] Specifically, the cylinder support frame 100 is welded by square tubes, and support plates 102 for facilitating the installation of the cylinder support frame 100 are provided at both ends; a plurality of support columns 401 are provided and are all fixed on the square tubes on both sides, and an installation space for the moving member 402 is reserved during assembly; two groups of cylinder surface support assemblies 200 are provided and are respectively located at the front and rear ends.

[0039] Furthermore, adjustable support feet 101 are installed at the bottom of the cylinder support frame 100.

[0040] It should be noted that the design of the adjustable support feet 101 facilitates the adjustment of the level of the cylinder support frame 100, thereby improving stability and ensuring assembly accuracy and efficiency.

[0041] Furthermore, the support seat 201 is installed on the cylinder support frame 100 through a screw rod lifting device 202.

[0042] Specifically, the screw rod lifting device 202 includes a lifting base 202a fixed on the cylinder support frame 100. A lifting handwheel 202b is installed on the lifting base 202a.

[0052] Specifically, a cross-shaped reinforcing plate 504 is provided in the middle of the annular plate 501. The fixing blocks 502 are L-shaped and are fixed to the annular plate 501 by screws.

[0053] It should be noted that by using the annular drilling jig with one drill hole as a reference, several other corresponding drill holes can be machined.

[0054] Further, it further includes a positioning pin 503 for positioning by inserting it into the radial drill hole.

[0055] Specifically, insert the positioning pin 503 into the drill hole machined on the ring rib connecting seat 402e5 to complete the positioning, and then cooperate with the annular drilling jig to machine the remaining drill holes.

Rotate the handwheel 402f corresponding to the lifting point connection seat 402e4, position and move forward to the positioning position, and fix it with the positioning pin 503. After the adhesive bonding and curing, use an electric drilling and tapping machine to drill holes and tap threads on the composite cylinder ring ribs through the self-provided radial holes on the lifting points, and tighten and fix with bolts.

[0065] 5. Installation of Metal Cylinder Limit Blocks

[0066] Use the threaded positioning pin 403 to position the two sets of limit blocks to the limit block connection seat 402e3 through the pre-machined plane and threaded holes on the bottom surface of the limit blocks. Apply adhesive to the assembly surface between the limit blocks and the cylinder. Rotate the handwheel 402f corresponding to the limit block connection seat 402e3, position and move forward to the positioning position, and fix it with the positioning pin 503. Wait for the adhesive bonding and curing.

[0067] 6. Drilling Holes in the Ring Ribs at the Tail of the Cylinder

[0068] Through the drill jig reserved on the ring rib connection seat 402e5, use an electric drilling and tapping machine to drill 2 radial connecting blind holes in the ring ribs at the tail of the cylinder.

[0069] 7. Product Dismounting from the Tooling

[0070] Loosen all the positioning pins 503 of the positioners, return the connection seats to their original positions, and hoist and dismount the product from above the tooling.

[0071] 8. Drilling Holes in the Ring Ribs at the Tail of the Cylinder
